Anthurium plant named ‘ANTHYTZEL’

ABSTRACT

A new  Anthurium  plant named ‘ANTHYTZEL’ particularly distinguished by having shiny, red, orbicular cordate and very durable spathes that retain the original color for a very long period of time, dark green and ovate-cordate, durable leaves, white spadix with yellow tips, early and continuous flowering throughout the year, and a plant height of 35.0 cm to 40.0 cm is disclosed.

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHYTZEL’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andraeanum L., and hereinafter referred to by the variety name ‘ANTHYTZEL’. The new Anthurium plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new 35.0 cm to 40.0 cm height plant with shiny and blistered, red, orbicular cordate and very durable spathes.

The new variety originated from a cross-pollination made in September 2006 in Bleiswijk, The Netherlands. The female parent was a red Anthurium pot plant designated ‘ANTHOLODOJ’ (U.S. Plant Pat. No. PP20,254), and the male parent was a red Anthurium pot plant designated ‘10619-01’ (unpatented).

A single plant was selected from the progeny of the stated cross in August 2008 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a 6-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Nov. 25, 2016. ‘ANTHYTZEL’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:

-   -   1) Shiny and blistered, red, orbicular cordate spathes;     -   2) White spadix with yellow tips; and     -   3) Green, ovate cordate leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 44-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in February 2018. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHYTZEL’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 44-week old plants which were planted from tissue culture in 14 centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in February 2018. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHYTZEL’ differs from the female parent plant ‘ANTHOLODOJ’ (U.S. Plant Pat. No. PP20,254) in that ‘ANTHYTZEL’ has ovate-cordate leaves and a wide spadix angle to the spathe, whereas ‘ANTHOLODOJ’ has elliptical cordate leaves and a medium spadix angle to the spathe. Additionally, ‘ANTHYTZEL’ has a spathe arrangement in which the distance between the highest flower and the highest leaf is 7.0 cm to 10.0 cm above the foliage, whereas the distance for ‘ANTHOLODOJ’ is 4.0 cm to 7.0 cm above the foliage.

‘ANTHYTZEL’ differs from the male parent plant ‘10619-01’ (unpatented) in that ‘ANTHYTZEL’ has ovate-cordate leaves, a wide spadix angle to the spathe, a mucronate spathe apex, and green cataphyll with red tips, whereas ‘10619-01’ has elliptical cordate leaves, a medium spadix angle to the spathe, a narrow acuminate spathe apex, and red cataphyll. Additionally, ‘ANTHYTZEL’ has a spathe arrangement in which the distance between the highest flower and the highest leaf is 7.0 cm to 10.0 cm above the foliage, whereas the distance for ‘10619-01’ is 5.0 cm to 8.0 cm above the foliage.

‘ANTHYTZEL’ differs from similar commercial variety ‘ANTHDASZUM’ (U.S. Plant patent application Ser. No. 15/731,361) in that ‘ANTHYTZEL’ has green cataphyll with red tips and ovate-cordate leaves, whereas ‘ANTHDASZUM’ has red-orange cataphyll and narrow long cordate leaves. Additionally, ‘ANTHYTZEL’ has shorter spadix than ‘ANTHDASZUM’.

‘ANTHYTZEL’ differs from similar commercial variety ‘ANTHABUDON’ (U.S. Plant Pat. No. PP20,282) in that ‘ANTHYTZEL’ has green cataphyll with red tips, ovate-cordate leaves, and orbicular cordate spathes, whereas ‘ANTHABUDON’ has red cataphyll, elliptical cordate leaves, and oblong cordate spathes. 

I claim:
 1. A new and distinct variety of Anthurium plant named ‘ANTHYTZEL’, substantially as illustrated and described herein.
